摘要

背景直到最近,耐多药结核病(MDR-TB)的治疗一直采用漫长而有毒的治疗方案。在吉尔吉斯共和国的一组耐利福平(RR)和 MDR-TB 患者中,我们研究了通过全基因组测序(WGS)和传统药物敏感性检测(DST)检测出的药物敏感性并用于治疗的药物数量对治疗反应(定义为 "匹配")的影响。结果研究纳入了 227 名 RR/MDR-TB 患者(30.8% 为女性;中位年龄 30.4 岁)。经年龄和性别调整后的分析表明,基线时有≥4个WGS匹配的治疗方案与治疗反应之间存在关联(调整赔率[aOR]2.10,95% CI 1.00-4.41)。结论我们的研究证实,在 MDR-TB 治疗方案中加入四种有效的抗结核药物可增加治疗反应阳性的几率。在 WGS-DST 中,至少四种药物的敏感性可预测阳性治疗反应。

Whole-genome sequencing drug susceptibility testing is associated with positive MDR-TB treatment response.

BACKGROUNDUntil recently, multidrug-resistant TB (MDR-TB) was treated with lengthy and toxic regimens. New three-drug anti-TB regimens raise the question of whether they are sufficiently active for MDR-TB in Central Asia, an MDR-TB hotspot region.METHODSIn a cohort of rifampicin-resistant (RR) and MDR-TB patients in the Kyrgyz Republic, we investigated the impact of the number of drugs that were tested susceptible by whole-genome sequencing (WGS) and conventional drug susceptibility testing (DST) and used for treatment on the treatment response, defined as 'matches'. Logistic regressions were performed to assess the effect of having ≥ 4 susceptible drugs in a regimen at baseline and at Month 2 on the treatment response.RESULTSThe study included 227 participants with RR/MDR-TB (30.8% female; median age 30.4 years). The age- and sex-adjusted analysis showed an association between a regimen with ≥ 4 WGS matches at baseline (adjusted odds ratio [aOR] 2.10, 95% CI 1.00-4.41). No association was found when using conventional DST to define matches.CONCLUSIONOur study confirms that the inclusion of four efficacious anti-TB drugs in an MDR-TB regimen increases the chances of a positive treatment response. Susceptibility of at least four drugs in WGS-DST predicts a positive treatment response..
